As electric vertical take-off and landing (eVTOL) aircraft move from concept to reality, they bring the promise of cleaner, quieter air mobility—especially in urban and suburban areas. From air taxis to regional electric aircraft, the vision is bold—but its success will depend heavily on how these vehicles sound.

Smart features, ultra-thin designs, and built-in DSP shape the future of vehicle testing

In Part 1, we looked at the transition toward 1/4” microphones, low-noise models for EVs, and rugged sensors built for harsh testing conditions. In this second part, we focus on cutting-edge features that enhance efficiency, reduce setup complexity, and support advanced automotive applications like CFD validation and in-cabin audio optimization.

在制造领域，有一个不变的因素：压力。规模扩张的压力。减少停机时间的压力。在全球生产线保持一致质量的压力。

对于参与最终测试的人员（无论是工程还是采购方面），声学验证只是整个流程中的一小部分，但却是至关重要的一部分。

经常被忽视的是，测试设备本身如何简化流程或带来不必要的摩擦。

Axiometrix Solutions 旗下汇集了 Audio Precision、GRAS Sound & Vibration、imc Test & Measurement 等全球知名品牌，专注于提供尖端的测试与测量解决方案。通过将这些品牌整合，我们为所有汽车测试需求提供一站式解决方案，帮助制造商和工程师避免因系统分散和多供应商管理带来的额外成本与复杂性。

The new gold standard in in-cabin acoustic testing is here, and it offers precision, practicality, and repeatability.

Over the past few years, we’ve seen growing demand in the automotive industry for accurate, standardized methods of performing acoustical measurements inside the car cabin. Whether it’s performance testing, characterization or optimization of automotive audio systems, analysis of a vehicle’s NVH behavior, or general cabin acoustics benchmarking, engineers around the world have been searching for a reliable solution—one that is easy to set up and capable of delivering repeatable results quickly. Until now, they’ve had to rely on DIY rigs, ad hoc configurations, or outdated tools that don’t match the sophistication of today’s vehicles.

That’s why we created the GRAS AutoArray—our new 6-Microphone Array, built for automotive engineers who are ready to improve their workflow and test results reliability in their in-cabin acoustic testing.
